Abstract

Singlet delta oxygen (1O2) was generated at atmospheric pressure using heterogeneous gas-phase photosensitization. Polycyclic aromatic hydrocarbons (PAH), known constituents of the atmosphere, were found to be efficient sensitizers in the production of singlet delta oxygen under simulated environmental conditions. A novel mechanism involving singlet delta oxygen is proposed in which PAH on particle surfaces are self-activated to form direct-acting mutagens.

摘要

通过多相气相光敏化在大气压下生成单线态δ氧（1O2）。多环芳烃（PAH）是大气中的已知成分，发现在模拟环境条件下，它是单线态δ氧生成过程中的有效敏化剂。提出了一种涉及单线态δ氧的新机制，其中颗粒表面的多环芳烃会自我激活形成直接作用的诱变剂。
